Here is a view of the future and it ain't pretty. Rest assured no viewer discretion is advised. There are no apocalyptic events, only widespread misery and horror. Although disasters may happen these will not be your main worry. No need to clean your weapons or open your canned veggies. It is unlikely that you will need them or even be able to use them.
Climate change is happening and it will have major effects on anyone living on the planet in the near future. We are already getting a first taste. Things are getting more expensive. You are having trouble making ends meet. "Consumer confidence is low. " Now, here is some good news. The present increases are unlikely to last. We will probably see some relief in the near future. The real trouble hasn't started yet and it probably won't for another decade or two. It is quite possible that we will go through another period of irrational exuberance first. A period where everyone will laugh at yet another doomsday scenario gone bust.
As I mentioned previously, a long world-wide recession lasting a decade or more, could mitigate this picture considerably. But to do away with it would require a substantial decrease in the world's population and that is unrealistic in my opinion.
When trouble finally hits, it will hit quickly and profoundly. Price increases will be swift and prices will mount on a daily if not hourly basis. Most will never see it coming. Wealth will be destroyed at breakneck speed. Soon, all of your income and savings will go to mere survival. That is, if you will have any income left. Or if people will still be willing to honor your paper money. Or your valuable possessions.
Tell me what is the value of a house in the desert when there is no water, or no air conditioning, and no services? What is the value of a house in the middle of nowhere, when nobody can afford to drive there any longer? What is the value of a car when gas prices are sky high and gas stations are running on empty?
These are not imaginary scenarios. Some of it we can see happening now, on a much smaller scale and to a much lesser extent. SUV's and big trucks are losing value. Homes away from population centers are in foreclosure, hyper-inflation plagues much of sub-saharan Africa and other poor nations. Now just imagine all these, all at once, and on a near-global scale. That is what you can expect.
Items will be more difficult to get, no matter how much money you have. Some items are likely to disappear altogether. Think fish for example, or meat. Your standard of living will erode away until nothing is left but bare existence. It will melt like the Arctic ice in a hot world.
Very likely, you will have to pack up and move to another more hospitable area to survive. Be sure to pack lightly because chances are you will have to walk there. Never mind, because most of what you own now has no value whatsoever.
Illness will spread and start taking its toll. Epidemics will sweep impoverished populations everywhere. The young, the old and the infirm will be the early victims. But it won't stop before taking a sizable bite out of the adult population.
No doubt there will be some demonstrations, skirmishes, and maybe some civil unrest. All of that is going to be an early phenomenon. It will have little impact and disappear quickly. It is little use to fight over nothing or to demonstrate against nobody. Most will rather flee than fight. If any fighting does occur, it will be in the form of a large-scale war. Such a war can only expedite the overall decline. Nevertheless, we cannot rule it out. A war could be the initial trigger. If China keeps growing a war becomes more plausible.
Given that much of our country is uninhabitable without cheap oil, it is doubtful whether anyone will want to stand up and fight for it. Quite the opposite is to be expected. People will be fleeing expanding deserts, flood plains, and wetlands. They will be moving out of areas hit repeatedly by wildfires or flooding. Massive refugee camps could become a reality for much of the world's population. But not for long. Such camps would be a fertile breeding ground for infectious disease. With little outside help, the number of survivors will quickly shrink.
However horrible, I still believe this is the most "benign" scenario. It is essentially a decline into a new middle ages. Although the scale and the scope is different it is much like what happened in Europe after the fall of the Roman Empire. Hopefully such a decline would be enough to allow the human habitat to recover.
The alternatives are not so good. Turning the earth into another venus is one such scenario. A mass extinction taking humans with it, is another, perhaps less dramatic one. While these are more Hollywood, I suspect they are extremely unlikely, at least for now.
